pub fn simple_bit_pack(w: u8, coeffs: &[i32; 256], out: &mut [u8])Expand description
Pack 256 coefficients, each using w bits, least-significant bit first within each coefficient,
coefficients in order 0 … 255, bit stream little-endian across bytes (FIPS 204 “SimpleBitPack”).
§Panics
If any coefficient is outside [0, 2^w).
